All burners should be thoroughly cleaned. Primary air openings

should be closed to exclude dust; louvers should be fastened in

a closed position. When equipment is disconnected from the

distribution system, the pipe openings should be capped or

blanked off. Weights should be removed from regulator arms.

Miscellaneous Equipment. In general, all exposed machined surfaces

not otherwise protected should be treated with rust-preventive compound or

paint.

Unit Heaters. Steam and water unit heaters should have supply

a)

and return lines disconnected; heaters should be thoroughly

drained. Oil and grease cups on fans and blowers should be

filled. When the construction of unit heaters prevents the

covering of motors, louvers should be tightly closed with

waterproof paper or plastic and tape. On gas or oil-fired

heaters, secure fuel lines outside the building line.

Pressure-Reducing Valves. Open and drain equalizing pipes

b)

between diaphragm chambers and low sides of systems, and

thoroughly clean the interiors of valves. Remove plugs from

drain holes, and leave drains open; loosen valves without

drains loosened to permit drainage of moisture. Open vents and

leave open on the low-pressure side of valves.

Strainers.

Strainers should be drained and thoroughly cleaned;

c)

drain plugs should be left open to permit drainage of moisture.

Radiators and Connectors. Completely drain radiators and

connectors, and tightly cap or cover all openings.

Steel Smoke Pipes and Stacks. Steel smoke pipes and stacks

e)

should be cleaned internally with a wire brush and coated with

discarded engine crankcase oil or mineral oil of similar

quality. Exterior surfaces not otherwise protected should be

coated with rust-resisting paint. If possible, stacks not

dismantled should have tops tightly closed off with metal caps

or boards. When the tops of stacks cannot be closed off,

stacks should be blanked off at boilers to prevent moisture

from entering smoke boxes and tubes. When blanking the stacks

from the inside of the smoke boxes, drains should be provided

to the outside. When smoke pipes or stacks are removed,

resultant openings in walls or roofs of buildings should be

closed with either wood or metal covers.

Gauges, Instruments, and Miscellaneous Parts. Gauges, instruments,
